Use of ISM bands in the UK

Just had this response from OFCOM about the use of ISM bands without a licence in the UK:

“The use of licence-exempt apparatus is authorised under exemption regulations, with set emission powers and other criteria.  This is in order for it to be available to all users with minimal risk of disruption or interference.

The limits, including maximum power levels and whether airborne use is permitted, are set out in the UK Interface requirement. If apparatus being used for testing meets the relevant technical criteria and complies with IR 2030, then a licence will not be necessary. Please note that some frequency bands which may be licence-exempt in other countries, such as the USA, may not be so in the UK and only the frequency bands listed are eligible for the exemption of qualifying apparatus.

In some circumstances we may be able to authorise the test or development of non-compliant radio apparatus under an Innovation and Trial (I&T) licence.  However, this generally will be under conditions that are sufficiently remote, shielded or otherwise unlikely to affect other users.  I&T is not intended for the operational use of radio apparatus, such as for the monitoring / control / telemetry of other apparatus, where a licensed or exempt authorisation is already generally available.  Even if it were the radio apparatus itself that is under test or development (in excess of normally permitted limits) we should emphasise that, as described above, it will not be possible to grant an operational permission for its future deployment and use.”

My reading of this is that as long as we meet the interface requirements set out in IR 2030, we are perfectly at liberty to use ISM bands for beacons without a licence.

At 8m, this means a limit of 10mW ERP.  10mW ERP does not sound much but on WSPR or FT8 range might be surprising.

This means anyone in the UK can use 8m (or any other ISM band) for beaconing as long as they fully comply with IR 2030.

I am not a legal expert and I have just shared what OFCOM has written in answer to my question earlier in the week.  In this instance, OFCOM has been very helpful indeed. I should like to thank OFCOM for the prompt reply.
